Engine dying when clutch is engaged
I've been having an issue for 2 years now. It would come rarely in the past. Recently it happens everytime I drive a certain way.
2 years ago:
The car had the 764/ 890 nm clutch kit with the RS LWFW, & a Europipe exhaust.
When I would slow down (pull up to a traffic light for example), if either the clutch is engaged or the gear is in neutral the rpm would drop below idle & the engine would die (the lights would come on also)
*Extra info: This was not after I upgraded my clutch setup, this was after 3 years of having this setup with no trouble*
Last year the car was tuned (intercoolers, y pipe, turbo inlet pips, catless europipe, meth kit and a custom tune) - done November '21
The last few months the engine dying has happened more frequently
I took the car in to diagnose the issue. MAF sensors replaced, Throttle body, alternator and ground cables, starter motor, all these replaced
I also "upgraded" my clutch kit as the car has been putting more power.
Clutch kit I went for was; Sachs 764 PP, Sachs Racing Clutch, and the RS LWFW
Recently the problem has become a lot more frequent.
Everytime I accelerate (any speed, any gear) what I noticed was that as long as boost builds up, then I let go of the accelerator and press the clutch, the engine dies.
If I do the same but accelerate gently (no boost builds up). the rpm will drop to idle or slightly above idle and then stabilize. The car will not stall unlike if I accelerate with boost. I'm not sure if that's related but the more info the better.
There are no fault codes... It's like chasing a ghost
I heard that the RS LWFW is not suitable because the GT2RS has a different crank and pulley which mates better vs the "standard" GT2. Also heard it's okay. imo i might install the GT2RS pulley. Again, not sure if that fixes this issue..
Anyone can help?

Need to move this to the correct subform.
I would say vacuum leak though.

Probably means the 997 Turbo subfurum.

I assumed he had a turbo and probably incorrectly. He probably has a GT2 but without context assumptions happen.
